Causes Anaplastic thyroid cancer is an invasive type of thyroid cancer that grows very rapidly. It occurs most often in people over age 60. It is more common in females than in males. The cause is unknown.Thyroid cancerThyroid cancer is a cancer that starts in the thyroid gland. The thyroid gland is located in the front of your lower neck.ImageRead Article Now Book Mark Article Anaplastic cancer accounts for only about less than 1% of all thyroid cancers in the United States. Symptoms Symptoms include:Cough Coughing up blood Difficulty swallowing Hoarseness or changing voice Loud breathing Lower neck lump, which often grows quickly Pain in the neck Vocal cord paralysis Overactive thyroid (hyperthyroidism)HyperthyroidismHyperthyroidism is a condition in which the thyroid gland makes too much thyroid hormone.
